3-Acetylthiophene

3-Acetylthiophene is an organic compound consisting of a thiophene ring substituted with an acetyl group at the 3-position. Its molecular formula is C₆H₆OS, and it appears as a colorless to pale yellow liquid with a characteristic aromatic odor. It is commonly used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals, agrochemicals, and specialty chemicals. Due to the presence of both a sulfur-containing heterocycle (thiophene) and a reactive ketone group, 3-acetylthiophene is valuable in research involving heterocyclic chemistry and functionalized aromatic compounds.
